"This kind of shift changes everything. It changes the publishing model, it allows smaller players to put out games, it affects DLC and it has a huge impact," PlayStation boss Shawn Layden said.

Also in the interview, Sony discussed PS4 Pro sales. While a unit figure was not disclosed, Sony said around 40 percent of PS4 Pro sales are from people upgrading from the standard PS4.

"People just want the best," PlayStation Europe boss Jim Ryan said. "Maybe they just want to future proof? I think we see the same thing from Apple customers too--there are people that want the best that you can buy."
